Title: Process for the manufacture of carbon black
IPC: C09C1/50
Filed: 1953-07-23
Abstract: <PICT:0738068/III/1> <PICT:0738068/III/2> Furnace carbon black is produced by introducing a gaseous or vaporized hydrocarbon and a gas comprising oxygen into a "whirl" chamber 3 of a burner 1, at least one of the reactants being introduced tangentially, whereby the reactants are thoroughly mixed, passing the resultant turbulent mixture through guide elements consisting of star-shaped arrangements of plates 7, 7a, &c., each of which is angularly displaced about its axis in relation to the preceding element, whereby the mixture emerges from the burner in substantial laminar flow, burning the mixture as a flame, withdrawing the mixture of carbon black and gaseous reaction products produced from the reaction zone, and thereafter recovering the carbon black.  The inlet pipes may be arranged as shown at 4 and 5 (Fig. 1), or 4 and 4a (Fig. 1a), oxygen being introduced at 5 and 4a respectively.  Alternatively the oxygen may be fed to the whirl chamber partly by pipe 5 and partly by pipe 4a.  Carbon deposition on the burner may be prevented by means of a jacketing tube 8 through which a scavenging gas, such as air, is passed so as to deflect the reaction from the edge of the burner. Alternatively mechanical stripper means may be employed.  A supplementary combustible gas, preferably containing free or combined hydrogen may be employed.  Sufficient oxygen for the complete combustion of the hydrogen, when present, is preferably employed. When oxygen substantially free from nitrogen is employed, superheated steam may be introduced into the reaction zone at a point at which the temperature is at least 1000 DEG  C., whereby an activated carbon black and reaction product gases containing carbon monoxide and hydrogen are produced, and the gases recycled to the process after condensation of water.  The bounding walls of the reaction zone may be of heat-reflecting, preferably ceramic material, between the flame and the point of introduction of the superheated steam, so as to calcine the black and produce a product of low empyreumatic content.

Title: Improvements in or relating to wetting, penetrating, foaming and dispersing agents
Filed: 1930-07-09
Abstract: Sulphonated aliphatic ethers, prepared by sulphonating alkyl ethers (up to the cetyl ether) of aliphatic unsaturated or polyhydric alcohols which contain one or more double bonds and/or free hydroxy groups and more than eight carbon atoms in the molecule are used as dispersing and fat-splitting agents.  By sulphonation, e.g. with sulphuric acid, oleum or chlor-sulphonic acid, under mild conditions, that is to say at a temperature of 0 DEG  C. or below, sulphuric esters are obtained, whilst the sulphonation of unsaturated ethers containing no hydroxy groups, at higher temperatures gives true sulphonic acids.  The products may be used alone or mixed with aromatic sulphonic acids or their salts, sulphonated oils, soaps or fat solvents, e.g. hydrocarbons or halogenated hydrocarbons.  In examples: (1) octadecenyl-n-butylether is sulphonated with sulphuric acid; (2) octadecyleneglycolmonomethylether is sulphonated with chlorsulphonic acid in the presence of trichlorethylene; (3) octadecenyl-isopropylether is treated with sulphuric acid in the presence of acetic anhydride.  Reference has been directed by the Comptroller to Specifications 343,872 and 343,901.ALSO:Sulphonated aliphatic ethers, which may be used in the textile and leather industries as wetting, penetrating, dispersing, and foaming agents are prepared by sulphonating alkyl ethers (up to the cetyl ether) of aliphatic unsaturated or polyhydric alcohols which contain more than eight carbon atoms and one or more double bonds and/or free hydroxy groups in the molecule.

Title: Improvements in or relating to electrical sound recording apparatus
IPC: B25F1/04
Filed: 1932-07-25
Abstract: 390,992. Sound-recording circuits. RADIO CORPORATION OF AMERICA, 570, Lexington Avenue, U.S.A.-(Assignees of Dimmick, G. L. ; Westmont, New Jersey, U.S.A.) July 25, 1932, No. 20909. Convention date,'Aug. 6, 1931. [Class 40 (iv).] An electrical sound-recording apparatus is provided with an electrically-operated monitoring indicator which-has frequency characteristics substantially the same as those of the recording mechanism. The indicating apparatus, shown diagrammatically by Fig. 2, includes a galvanometer 1 which vibrates a mirror m and a light source 2, light from which passes through an aperture 4 and is then focused by a condenser lens 5 upon the mirror m. The reflected beam from the mirror m is further reflected by an adjustable mirror 6 and by a mirror 8 to impinge upon a viewing screen 9. The mirror 6 is adjusted by a member 7 so that in the normal position the reflected beam falls upon the mid-point of the screen 9. The output from the recording amplifier is supplied to transformers 11, 12 the transformer 12 operating the recording mechanism at 13 and the transformer 11 actuating the indicating apparatus. The galvanometer 1 is designed to have electrical and mechanical characteristics similar to those of the oscillating member of the recording mechanism and a resistor 14 is used to vary the sensitivity of the indicator to match that of the recorder. The apparatus is assembled as shown in Fig. 1a and is enclosed by a cover which is furnished with an internal screen for the light source 2 and with an aperture through which projects the member 7. An observation port in the cover allows the position of the light beam upon the scale of the screen 9 to be observed.

Title: Improvements in the drying and calcination of siliceous substances
IPC: F26B3/00
Filed: 1920-07-13
Abstract: Siliceous residues having absorptive properties and resulting in the extraction of alumina from shales, fireclays, &c. by means of sulphuric acid are dried and calcined by slow combustion of carbonaceous matter contained in or mixed with the residues.  The material is heaped over air channels formed of loosely laid brick courses and ignited by a small fire previously started over the channels.  As the mass burns through, additional quantities of the residues are slowly added.  Instead of treatment in heaps, a kiln arranged for charging at the top, and discharging at the bottom, and having air inlets near the bottom, may be employed.  A forced draught may be applied to the brick channels or to the kiln.

Filed: 1945-08-18
Abstract: <PICT:0597449/III/1> The process for the distillation of tars to pitch as described in Specification 472,541 is adapted to the production of hard pitches by placing that portion of the circuit comprising the flash chamber 12, pipe still 11 and interconnected piping under vacuum. The vacuum is applied by means of a pump 24 through condensers 27, 28 to the pipe 13 leading from the flash chamber 12 to the fractionating column 8 the condensate withdrawn being sent to receivers 29, 30.  The circuit shown in double lines is thus maintained under vacuum.  Valves 14, 161, 171 are provided for closing the normal conduits 7, 16, 17 to the column 8, distilling column 2 and draw off line 17 respectively when the vacuum is in operation.  The tar in the flash chamber 12 is reduced to hard pitch by steam injected through perforated pipes 26 and the pitch is withdrawn by a pump 25 through the discharge line 19.

Filed: 1938-07-16
Abstract: 502,778. Stapling. HANSEN MANUFACTURING CO., A. L. July 16, 1938, No. 21198. Convention date, March 14. [Class 89 (iii)] A stapling tool provided with a yieldable front wall for the driver passage, comprises a base 10 and head 12 formed from a single sheet of metal, a handle 11, a driver plunger 13 operated by springs 14, and a lever 15 for raising, and then releasing, the plunger by means of links 16 and a pawl 17. The yieldable wall 29 is provided by a U-shaped member 40 which embraces the lower end of the head and is pivoted to bent links 42 which, at their upper ends, are pivoted to a cap 33 which closes the upper end of the head and is free to slide thereon to an extent controlled by a stud 35 and slot 36. Normally, the member 40 is held in working position, Fig. 3, by a catch 45. When the lever 15 is operated to raise the plunger 13 and drive a staple, the pressure of the springs 14 against the cap 33 acts, through the links 42, to hold the member 40 firmly in position, Fig. 5. It can, however, yield in the event of clogging. By depressing the cap 33 against the springs 14, the member 40 can be moved out of engagement with the catch 45, and can then be swung forwardly to expose the driver passage.
